Application filed December 14, 1916. Serial No.. 137,025.

Io all who/m, t may concern:

Be it known that I, Crans M. .rrnnon'n a citizen of the United States, f iiding at North Yakima, in the county of Yakona a State of Washington, have invented c new and useful lmp] -venienrs in il Leaf Turners; and l do hereby declare the following to be a full, clear, and exact d1,- scription of the invention, such as will able others skilled in 'the a rt to which it pertains to make and use the saine.

This invention relates to music leaf turners and has for its principal object to provide a device of this character whereby the leaves of sheet music or music in book form may be turned consecutively from the right to the left while 'playing the music and embodying means wherely all of the leaves turned may be simulta; eously turned t; the right or to their original position.

Another object of the inv ntion is to provide a device of this chai er cnibodjf'ing a plurality of music loaf turner arms that are detachably engaged with the tm'ning mechanism.

A further object of the invention is to improve and simplify devices of this character so as to be of comparatively inexpensive construction, of durable and substai'itial de* sign, and one which may be readily and quickly manipulated in an eliicient manner.

With these and other objects in view as will appear as the description proceeds, the invention comprises the various novel features of construction, combination and arrangement of parts as will be more fully described hereinafter and set forth with particularity in the appended claims.

Referring to the drawings.

Figure l is a perspective view of my improved music leaf turner.

Fig. 2 is a vertical. sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2.

Similar characters of reference are used to denote like parts throughout the accompany ing drawings.

Referring more particularly to the drawings, the reference numeral 1 indicates the base board of my improved music leaf turner, upon which is mounted a frame work 2 by screws or other suitable fastening means 3, this frame work being preferably located adjacent the bottom of the base board. This frame work 2 is provided at the bottom portion thereof with a pair of downwardly and outwardly curved supporting arms 1, in the outer ends of which is supported and horizontally disposed a shaftand upon which is pivotally mounted a. plurality of substantially L shaped operating keys G, the outwardly extending horizontal portion of these keys being provided Vwith a linger piece whereby they may be rocked upon the shaft 5 to operate the mechanism to be hereinafter described.

Extending upwardly from the upper part of the frame work' 2 are a pair of arms S, the upper ends of which are each provided with a socket 9 which is'adapted to receive the lower tapered ends of a retaining bar 10, that is disposed vertically upon the base board and extends upwardly to a point adjacent the top thereof. These retaining bars 10 are arranged in substantially parallel lation to each other and are adapted to be positioned over the cover leaves or l a'cks of the music that is positioned upon the base board 1 to be played, these bars being spaced apart suliiciently to permit the leaves of the music to extend upwardly therebetween in order that they may be grasped by the music leaf turner arms which will be presently described. The base board 1 is further provided with a pair of horizontally disposed shelves 11 which are positioned, on the opposite sides of the sockets 9 carried by the arms 8.

Bearing brackets 1Q and 18 project outwardly from the base board 1, and rotatablyY mounted in the hearing bracket 12 is the lower end of a vertically disposed shaft 14, `vhich is provided with a bearing collar 15 adjacent .its lower end that is designed to rest upon the lower bearing bracket 12. The lower end of the rotatable shaft 1st is provided with a grooved pulley 16 which is keyed. or otherwise fixed thereto and rests upon the bearing collar 15 which latter also serves to space the grooved pulley from the bearing bracket. The upper end of the rotatable shaft 14 extends upwardly to a point beyond the bearing bracket 13 and has keyed thereto or otherwise fixed a circular head block 17, to the peripheral edge of which is attached a vertically extending substantially V shaped socket 18.

Surrounding the shaft 14: is a rotatable tubular shaft 19, the Vlower end of which rests upon the grooved pulley 16 and is provided adjacent, this lower end with a grooved pulley 20 which is securely fixed thereto, the upper end ot Said tubular shaft extending upvvardly to a point adjacent the head block 17 so as to be in space l relation thereto and has fixed thereto a head block 21 similar to the head block 17, and is likevvise provided with a substantially V shaped socket 2'?. which is ot a length slightly greater than the socket 1S.

Surrounding the tubular shaftl 19 is a rotatable tubular shatt Q3, the loiv r end ot ivhich rests upon the grooved pulley Q0 and carries adjacent its loiver end a grreoved pulley 2l which is fixed to the tubular shatt for rotation therewith. rEhe upper end ot this tubular shaft is provided ivith a circular head block 25 that is lined thereto and rests upon the upper surface ot he hearing bracket 13. in Which the tubular shaft is journalcd for rotation. lThe peripheral edge of the circular head block is also provided with a vertically V shaped socket 2G ivhich is ot a length slightly greater than the socket 22.

rhe device shovvn is constructed to turn three music leaves consecutively through the medium of the operating keys QT, QS and 29 respectively. a kei7 BO being` employed to reverse or move all ol the leaves that have been turner back to their original position simultaneously. The vertical extending portion or" each oithe substantially L shaped keys` increases in height from the first to the third or last key. and as clearly shovvnj the;7 are each connected to their respective pulleys 1G, Q0 and 2l through the medium ot cables 31, which extend halt vvay around each ot the `e'roovcu pulleys and are securely fastened thereto by a staple or any other suitable fastening means The loiver cable 31 that extends around the ggrooved pulley 16 'from the operating` key '2T is eX- tended around and beyond the pulley and has its terminal end connected to the upper end 33 ot the reverse key 30. vvhereby all ot' said circular head blocks may be rotated back to their original position after they have been once operated in the course oi turning the music.

Detaehablv eneafed with each ot the sockets 18. 22 and QG is a vertically extending; music leat turner har 3l, the loiv r end of which is tapered and is designed to vvet {ringly engage within its respective socket. These turner bars 34 have connected to them adiacent their lower ends and the upper ends of the sockets in which there are mounted horizontally extending music leaf turner arms 35. the outer ends of vvhich may or may not as desired be provided with spring Ciampino' Vingers hetiveen which the loiver edges ot the music leaves may be hold ivhile heine' turned from one position to another. The upper ends ot each ot the bars are provided in one of their side edges with ay series of ratchet teeth 3G ivhich are designed to he engaged by the inner beveled Wall 37 Ot an operator arm 3S, which is Slidebly positioned over the upper end of each or" these turner arms. As shown, the arms Y35 extend horizontally and have their outer 'free ends provided with spring clamps 39 which are designed to grip the outer edges ot the music leaves.

By the particular construction of the inner ends oi' each ot these arms 3S and the upper ends ot the bars 34, it will be apparent that the arms can be adjusted vertically upon the bars 3l and held in such adjusted position through the medium of their oivn Weight. The base board l is further provided ivith bowed springs dft) securely attached at one end to the hase hoard and positioned upon the opposite sides oit the retaining bars 10, and it is to be understood that these springs Ll() are designed to press the music leaves outwardly against the music leat turner bars and their respective arms and thus preventing the leaves trom sagging in the middle.

In the operation ot the device the music is placed upon the base board 1 and on the shelves 11 thereoll and the retaining hars 10 are then positioned over the cover leaves ot the music and engaged with the sockets 9 so as to be tirmly held in position to retain these cover leaves upon the base board and at the same time permit the music leaves to extend outwardly between them into position to be engaged by the leaf turner arms. The cover leaves having' been positioned in fixed relation to the base board, the leaf turner bars 3l, ivhich each carry the arms and 3S are each positioned over and attached to each succeeding leaf irom the rear cover leat to the front cover leaf. atter which their lower ends are engaged in the sockets 18. 22, and QG. The turner bars 3l having` been arranged in position over each ot the music leaves. the device is non' readv to operate in order the turn the leaves trom the right to the lett. lllhen it is desired to turn the tirst sheet et music over. the key member QT is depressed ivhich vvill rotate the pulley 1G carried bv the loiver end ot' the rotatable shaft 14. this movement rotatingr the head block 1T ivhich carries the V-shaped socket 1S and in which is positioned the outermost or first et the turner bars 3l. whereby it will be seen that the iirst leaf of music will be. moved from the right to the lett. Likewise each successive sheet is turned from the right to the lett hy the depression of each succeeding key 2S and '29. Non' in order to reverse the movement ot the turner bars or in other vvords to move the music leaves 'from the lett to the richt or their original position. the reverse key 30 is depressed which ivill rotate the ,grooved pulley 1G in a reverse direction to the direction in which li U it Was originally moved, which will rotate the socket 18 from the left to the right also moving the sockets Q2 and 26 positioned upon it over to their original position.

It is to be understood that the Weight of the arms and 38 together with the bars 34 will be suliicient to retain the music leaves upon the right hand side ot the device against the liability of bei-ngI accidentally turned through the medium of Wind or any other means. However, should the weight of the bars and arms not be sullicient to held the music leaves in position on the right side of the device, I propose to employ a series of spring arms 41 that have their outer ends securely attached to the frame Work Q, and their inner ends engaging behind lugs L12 formed on the upper surfaces of the grooved pulleys 16, 20 and 24, these spring arms exert an outward tension behind the lugs 42, tending to urge the pulleys around te the right which in turn will cause the said turner bars to be firmly pressed to the right against the base board 1. W'hen the operating keys have been depressed and the music leaves turned to the left, the Weight of the keys will serve in addition to the weight of the turner bars and arms to positively maintain them in turned position.

1. A music leaf turner, comprising a base board, a frame Work mounted thereon, bearing brackets extending from the base block, a plurality ot shafts telescopically mounted in said bearing brackets, a grooved pulley carried by the lower end of each of said leaf turner arm attached to each ol said cir cular head blocks, a lug formed on each et' said grooved pulleys, spring arms attached to said frame Work and engaging behind said lugs and adapted to urge said pulleys to the right te hold the music turner arms upon the music leaves, means for rotating said pulleys consecutively in one direction, and means for rotating all of said pulleys simultaneously in the opposite direction.

ik music leaf turner comprising a bas-e board, a frame `Work mounted thereon, beara ing brackets extending from the base block, a plurality of shafts telescopically mounted in said bearing brackets a greoved pulley carried by the lower end of each of said shafts, a circular head block carried by the upper end of each said shafts, a music leaf turner arm carried by each circular head block, a bracket projecting laterally from said frame Work, a plurality of L-shaped operating keys pivotally mounted in said bracket, and flexible elements connecting the upper ends of said L-shaped keys to said grooved pulleys whereby each of said music leaf turner arms may be consecutively and simultaneously actuated,

In testimony whereof I have signed my name to this speciication in the presenceot two subscribing witnesses,

CYRUS M. APPLEGE'.
